SOLUTION

var eq1 = A + "x + " + B + "^\\circ";
var eq2 = C + "x + " + D + "^\\circ";

init({
range: [ [ -1, 5 ], [-1, 1] ]
});
graph.pl = new ParallelLines( 0, 0, 4, 0, 0 );
graph.pl.draw();
graph.pl.drawTransverse( ANCHOR );
graph.pl.drawAngle( KNOWN_INDEX, eq1 );
graph.pl.drawAngle( UNKNOWN_INDEX, eq2, "#FFA500" );
"
